SUPPORT FOR PUNCHING-BAGS.

Specification of Letters Patent.

Patented Oct. 15, 1907,

Application filed Febr a y 16,1907. $erial No.357,738.

To all whom it may concern:

Be it known that l. ROBERT A. HART, a citizen of the United States ofAmerica, residing at West Liberty Borough, in the county of Alleghenyand State of Penn sylvania, have invented certain new and usefulImprovements in Supports for Punchingdiags, of which the iollowing is aspecification, reference being ha therein to the accompanying drawing.

This invention relates to supports for punching-bags or similar tlexibleexercising devices, and the invein tion has for its object to provide anovel swivel for supporting a punchingdmg, thereby eliminating orreducing to a minimum lriei ion caused between the movable punching-bagand it.-; permanent support.

Another object of my invention is the provision of positive and reliablemeans ior normally maintaining a punching-bag a predetermined distancefrom its rebounding device.

A further object of this invention is to overcome the binding ol themovable parts ot a bag during the movement thereof, thus providing afree and easy movement of the suspension cord or rope oi said bag.

With these and other objects in view which will more readily appear asthe invention is better understood, the same consists in the novelconstruction, combination and arrangement of parts to be herein aftermore fully described and then specifically pointed out in the appendedclaims.

Referring to the drawing forming a part oi this specification, likenumerals of reference designate corrc-' spending parts throughout theseveral views, in which:-

Figure '1. is an elevation of my improved punchingbag support, Fig. 2 anenlarged elevation of the support, illustrating the suspension rope inan elevated po-. sition, Fig. 3 is a vertical sectional view of thesame, illustrating the suspension rope in its normal position, Fig. t isa cross sectional view ol the base plate of my improved support, andFig. 5 is a plan of the same.

My punching-bag support comprises a base plate 1. preferably circular interm and having a plurality of screw openings 2 whereby the base platecan be secured to the ceiling, wall. lloor or rat'ters of a compartmentoi building, such as a gymnasium. The base plate is provided with acentral enlargement 3 having a vertically disposed threaded openingformed there in, to receive the threaded end 5 of a depending sleeve 6.The sleeve t5 is provided with a central bore 7 having curved edges 8 atone end thereof, while the opposite end 01' the bore terminates in asocket 9 formed in the threaded end 5 of the sleeve.

The suspension rope or cord 10 carrying a conven-' tional form ofpunching-bag ll, is provided with an adjustable ball bearing 12, a screw14 carried by said ball bearing engaging the suspension cable or rope,

which passes through an opening 15 formed in said ball bearing. Easyaccess is had to the screw 14 when the bearing 12 in its socket, throughthe medium of a slot 16 formed in the threaded end 5 of the sleeve 6.

It is a well known iact, especially among professional bag punchcrs,that the suspension ropes or cables thereby become stretched, causingthe position of the pun clung-bag with relation to its rebounding deviceto vary. To overcome this, I have devised the adjustable ball bearingwhich can be easily and quickly adjusted upon the suspension cord orrope 10, to support the punching bag at a predetermined distance fromits rebounding device, which in the present instance is a ceiling. Theball bearing 12 not only serves as an adjustable support for thesuspension ,rope or cord 10, but serves functionally as a swivel,allowing the punchingbag to swing in any desired direction withouttwisting the suspension cord or cable.

My invention entirely resides in the novel construction of the sleeve 6and the manner of holding the suspension cord or rope oi thepunching-bag therein, and i'or this reason I do not care to confinemyself to the type of punching-bag used in connection with the support.

Such changcs in the size, proportion and minor details of constructionas are permissible by the appended claims may be resorted to withoutdeparting from the spirit and scope of the invention.

What I claim and desire to secure by Letters Patout, is:

it In a support for punching bags, the combination with a 1)llll(flllll.:-l)il3,' and the suspension cord or rope thereof, of a base plate, asleeve threaded in said plate, said sleeve having a bore formed thereinterminating in a socket, said sleeve having a slot formed thereinadjacent to said socket. and a ball bearing adjustably connected to saidsuspension cord or rope and seating in said socket.

ln :l support for punching-bags, the combination with a punching-hag andthe suspension cord or rope thereof, of

a sleeve, said sleeve having a bore formed therein termt hating in asocket, a ball bearing adjustably connected to said suspension cord orrope, and seating in said socket, 7

means td adjust: said ball bearing, and means to support said plate.

1;. A punching bag support consisting of a base plate having a dependingcentral enlargement. a sleeve threaded into said enlargement having; asocket in its upper end and provided in its side with a. slotcommunicating, with said socket. a hall mounted in said socket andprovided with a central opening, a suspension cord for a punching bagpassed through said central openingin the ball, and means accessiblethrough the slot in said sleeve for ad- ;instably securing said cord tosaid ball.

In testimony whereof I aflix my signature in the pres ence olf twowitnesses.
